BottleRock Napa Valley has become one of California’s top music festivals in just three years.

It’s easy to understand why, once you get a look at this year’s impressive cast of headliners, which includes classic-rock icon Robert Plant, multiplatinum pop outfit No Doubt and popular rock band Imagine Dragons, who will appear May 29-31 at the Napa Valley Expo grounds.

But the music is only part of the appeal. The setting — in the heart of downtown Napa — is a major factor, too.

In addition to the city’s many dining, wine tasting and shopping charms, the festival itself includes a bounty of food and wine delights. You can grab a glass of Schramsberg bubbly or Del Dotto cab, pair it with noshes from Morimoto, La Condesa or other culinary destinations and then rock out to the tunes onstage. It’s a combination that defines the BottleRock experience and draws tens of thousands of fans to the music fest.

The festival is set on a flat, easy-to-navigate 26-acre plot with four stages, all in fairly close proximity, which helps maximize the time spent rocking over the time spent walking. That’s a huge plus for this kind of festival, where fans constantly are moving from stage to stage. It also makes for a comparatively intimate affair. With a capacity of 30,000 to 35,000 per day, it’s far less of a crush than what you’ll find at many major rock festivals.

And then, of course, there’s the music. The headliners are a major draw, but the undercard is just as appealing, with legendary rapper Snoop Dogg, critically acclaimed folk-rock act the Avett Brothers, hip-hop heavyweights Public Enemy and indie-pop sensations Foster the People among the more than 70 artists scheduled to appear at this year’s event.

It’s a lineup that should appeal to a wide range of listeners — which was the goal.

“It’s hip, but it’s not too edgy,” says Dave Graham, CEO of the Latitude 38 Entertainment group, which runs BottleRock. “We want this festival to be approachable to everyone.”

Of course, what you get out of BottleRock has a lot to do with what you’re willing to pay. General admission is $119, or $275 for the three-day fest. But festival organizers put major effort into crafting memorable experiences for VIP ticket-holders (three-day VIP tickets are $595), with prime shaded seating at concerts, expanded wine and food offerings and parking.

Those really looking to party like a rock star — and who can afford to do so — can grab a three-day platinum pass for $3,000, which includes on-site concierge service, air-conditioned lounge areas, exclusive tasting menus and rare Napa Valley wines served by some of the world’s top sommeliers.

But any way you get through the gate, you’re sure to have a rocking, sipping, noshing good time.

BottleRock Napa is known for its distinctive combination of music, food and wine. Here’s what — and who — you can expect this year. Note: Some of the more upscale food and wine experiences are reserved for VIP and premium ticketholders.
